An iron-catalyzed sulfonylation of aryl enol acetates with sulfonyl hydrazides enables the construction of β-keto sulfones under aerobic conditions. This environmentally benign approach utilizes an inexpensive iron salt as the catalyst, readily available sulfonyl hydrazides as the sulfonylating reagents, and air as oxidant under mild conditions.
